Well-made Ovaha, it is a pity that it is a fragment of a big story, which still has a manga and a novella.
A group of schoolgirls walk through the post-apocalyptic world of the future. Finds old familiar details from his daily life and notes from his long-dead friends.
Despite their claims that they passed the exam to be on this intertemporal expedition, it quickly becomes clear that they were not given specific tasks. They don't know what to do in this future without humans, or how to survive in the wild. Issues of planet repopulation are also discussed in the film, but the boys could not pass a strict selection for the expedition, so it turned out to be a same-sex.
Thus, OVAHA is a half-hour walk of schoolgirls in unstained form through the ruins of civilization and philosophical conversations. There are also obvious references to the manga and the novella (movie, photo on the phone, the phone itself). But they are not clear apart from other parts of the trilogy.
Such a move causes me mixed feelings. Overall, it looks interesting enough to read it someday. Separately, I wouldn’t recommend it to anyone.
